[Mailman-Users] Catholic Information Network (CIN) Moderators List flooded with blank emails

[Norbert Bollow]

Obviously, check the maillog carefully.  What triggers the
generation of these messages?  Are you using demime or some
other tool in a pipe to Mailman, that might choke on some
types of messages?

(One way to create a bounce-loop is to use demime on the list-admin
address, and have one list-owner's email address generate bouces
of a MIME type that demime cannot handle... this type of
bounce-loop will flood the other list-owners with empty messages
like you have described.)

Greetings, Norbert.
